Abstract:
A method is suggested for the simultaneous personalization of several portable data carriers (2) respectively having at least one integrated circuit (6) for storing and/or processing information. According to the invention a unidirectional protocol serves for transmitting an identical personalization signal to several portable data carriers (2). These detect personalization data on this basis and store them in the integrated circuits (6). Preferably adapter elements (100; 101; 102) are used, which can accommodate at least one data carrier (50) and which are equipped with first interfaces (140; 150) for communicating with a reading device (20; 21; 22) and with second interfaces (120) for communicating with the accommodated data carrier (2). In a variant the portable data carriers (1) are transported in a transport device (600) which, at least temporarily, electrically contacts the contact area (9) of the portable data carriers (2) by means of a contacting unit (604).
Abstract:
The present invention relates to the use of comb polymers which have a carbon backbone which bears polyether groups of the formula A *—U—(C(O))k—X-(Alk-O)n—W A wherein * indicates the binding site to the carbon backbone of the comb polymer, U stands for a chemical bond or an alkylene group with 1 to 8 C atoms, X means oxygen or a NR group, k is 0 or 1, n stands for a whole number, the mean value whereof, based on the comb polymer, lies in the range from 5 to 300, Alk stands for C2-C4 alkylene, where Alk within the group (Alk-O)n can be the same or different, W means a hydrogen, a C1-C6 alkyl residue or an aryl residue or means the group Y—Z, Y stands for a linear or branched alkylene group with 2 to 8 C atoms, which may bear a phenyl ring, Z stands for a 5- to 10-membered nitrogen heterocycle bound via nitrogen, which can have as ring members, as well as the nitrogen atom and as well as carbon atoms, 1, 2 or 3 additional hetero atoms, selected from oxygen, nitrogen and sulfur, wherein the nitrogen ring members can contain a group R′, and wherein 1 or 2 carbon ring members can be present as carbonyl groups, R stands for hydrogen, C1-C4 alkyl or benzyl, and R′ stands for hydrogen, C1-C4 alkyl or benzyl; and functional groups B, which are present in the form of anionic groups at pH>12, and salts thereof as grinding aids in cement-containing preparations.
Abstract:
Water-soluble or water-dispersible polymers comprising alkoxylated diallylamine derivatives, ethylenically unsaturated mono- or dicarboxylic acids, the anhydrides thereof or mixtures thereof and, if required, one or more further ethylenically unsaturated monomers C are prepared and are used as additives in mineral building materials, in detergents or in cosmetic formulations.
